'Day time' in the Bible

O my God, I cry in the daytime, but thou answerest not; And in the night season, and am not silent.

Yet Jehovah will command his lovingkindness in the day-time; And in the night his song shall be with me, Even a prayer unto the God of my life.

In the day-time also he led them with a cloud, And all the night with a light of fire.
